Did the people at Johnson Johnson or DePuy Orthopaedics know that there were problems with the hip implants?

The recall comes more than two years after the Food & Drug Administration began receiving complaints and follows a determination that the failure rate for both DePuy ASR acetabular cups was more than 12%. The actions follow extensive reports of hip replacement pain and failures from the defective products and ask for medical and orthopaedic surgeons to monitor their patients more closely.
